Such movemenil is effected along' the yarn receiver for e pora tion only of the length of the letter, 'seii movement being generally termed the treversei 1"agi-3 is bliiitby shifting iile The pee mii; of iiie relativo i'ioovemeii progressively miens he axis of theyein receiver. This shift is geueiiiiiy tei-med the gaine In iii@ formation of such @yarn package, e iiifiximiiiii diameter is reached at e poin'iI :i ve .base due to the cooperative eii'eci; of alie u'iveise and the gain.

in accordance with my invention, iie ige wound and formed with eficiency in :i winding imspiniiing or twisting mechine` :mii when Wound in i spinning o11 twisiing machine the tension oi the yam is conti-died :ind the iajvf oi' the yarn is wei: thereby beneited, In Jshe formation of the base of the package, the successive layers ot "yarn areso laid one over the other until the full'diametero the package is reached that each bottom coil of each layer is laid safely upand above the bottom coil of the preced ing layer (assuming the yarn receiver to be ,upright and the yarn to be Wound thereon from, the bottom upward), and While the ,basal portion of the lyarn package is so ',cha'racterized, preferably' the same Winding e'ect is continued throughout the entire l lengtliof the package. This feature of the winding is accomplished in the disclosed. em

:bodiment 'of the invention by increasing the vgain and preferably by incrementally. increasing the gain throughout the formation of the base of the package. Throughout the body ofthe package the gain, in the disclosed embodiment oi the invention, is such as to maintain the body of the package solou stantially cylindrical. ln that type o' the i f invention ydisclosed the gain throughout the body is substantially uniform. By increasing the traverse throughout the formation of the basal portion of the pack age, and especially by increasing the traverse throughout the lformation ci" the entire package, as is elicctcd in the disclosed embodiment ol the invention, each smoes sive layer of yarn is laid over a slightly y greater extent axiallyof the package than the .layer just preceding. Due to the con stent speed of thef spindle or other yarn receiver, and in ring frames particularly, dus to the constant speed of? the iced rolls,

' if each traverse is effected in the'same pew riod of' time, then with ymore rapid] each succeeding layer, the coils thereof' are a little more Widely separated. u I

lf theyarn 'package be formed in a ring spinning frame, then by increasing the lin; ear speed of the ring rail progressively, refsulting-from'an increasing traverse .in con-V stanttiine l idfof the cop, andl there `such place. vw(ltherwisest'ated, the spec'dol thetraifeler llistin'aintained more ,near y stant andv therefore the .tensioni on they yarn is mailitainedy morenearly constant; Presi erably ethegainfand the increase in traverse are ezccted during, the last portion ot 'the 11p-stroke, so that' this increased linear movement or' the ring rail added at such time; The result is that the ring?1 rail may be operated with large incro "c .in the number otits reciprocations du ng a given time and the yarn wound with' much more 'uniform tension and. with do ,reas-ed yarnbreakage.

The result of the formation of a yarn package in accordance with mymcthod is that the increase in traverse from base to the bare,- spin i'smoredfeach time: K vthe spinning flowing'r .thereby conf niniilierot "coils: laid speed in menace nose gives reversely a decreasing taper from nose to base., so that the yarn Withdrawn by draft axially of the package is drawn from a surface on the package approaching more and more nearly to a surface at right angles to the axis of the package. Thereloro, as the length of yarn extending from the-surface Wherfrom it is being delivered to the point above the package, Where draft is being applied to the yarn tends to increase and ballooning of the yarn away from the axis of the package tends to in crease,'such tendency to increased balloonl Aing; eilect is checked because the yarn draws from a surface approaching more and more nearly to a flat surface right angles to the axis of the package. Vvhen the yarn package is in a shuttle, such formation checks the tendency of the yarn to balloon out and contact with the sides of the shuttle, and thereby decreases breakage. Furthermore, as the base of the package is reached in the 'un'winding (and. throughout the entire package when the increase in gain is established throughout the entire package) each bottom coil of each layer (having been 4 safel laid b means of the increase in ain over and above the bottom coil of the preceding layerl is permitted to be Withdrawn Without fouling Withfand tending to Slough oli the preceding layer. These advantages thus secured in the unwinding are of great practical' importance in Weaving where the yarn is subjected to quick, intermittent draft, reaching a speed from live to ten yards a second.

lWhen the yarn package is spun or formed .in a ring; spinning; frame, the latter is provided With a ring;r rail and with continuously rotating;l yarn receivers in the form of spinning' spindles haring bobbins of paper or similar *tubesv thereon. lNithin the scope of my invention,V the yarnlfeceiver may be die."` Th s t 'ing .A ailcarryingf nir fandjl travelers may fco'ndit "etitutcyarn'.guiding meallvsfgand :in :vx-coord- 'an ce wi th' my' nvei'ition I kcauscia, rel ative VLto Vand 'tro traversemovement b.

Thus Isecure the even paying oli' of the yarn.

In accordance with my invention, the incremental increase in the during the completion o the upstrolre of the traverse, and since the increase in the traverse increases the general s eedof the ri ng rail during the traverse, it olloWs that the traverse is speeded up just as the ring rail is completing its up-stroke. The result to secure the proper laying of the yarn by tending first to keep the coils of each layer laid well above each other at the top and second to reduce the number of coils laid at the top,-that is, when the yarn is being wound upon that portion ol" the receiver of smallest diameter, and hence when yarn breakage lis most apt to occur. The number of coils laid at the top portion of each traverse, that is, the number of coils laid in the top portion of each layer, is rcduced in the practice of lmy invention, inasmuch as the number of coils laid at any portion of the yarn .package varies inn iersely as the speed of the ring rail in traversing such portion of the package. The similar increase in the speed of the ring rail at the upper portion of each traverse, that is, in the formation of the upper portion of each layer, not only 'tends to com pensate for the inherent tendency of yarn v spinning mechanism to lay more Winds of yarn at the upper portion of each traverse,-

ille yarn pacli'agc is wound with reduced that is, on the portion of the yarn receiver oi least diameter, but it also tends to coinpeusate for the lag; of the traveler nt the upper portion of the 11p-stroke oi the ring y'ail with the result of less variation in the spoed of the traveler, due toits lng; al; this portion. oi the upc-stroke.` l After .the yarn has been coilednt the extreme tip ol`each layer, it Hiermit@ returnedquickly therer from in the laying* ivi'fftliof-rnjext. layer; Thus,

yarn breakage and Awith a more uniform tension throughout.l -Altho1igrli Ihave hereinV referred. to the increase in the traverse as constant, it is to be understood that thereby is meant a. regula r increase, inasmuch as in practice the traverse is' not increased :it `all instants ol time duringr the operation of the mechanism or the carrying'. out of the method, but preferably vonly at a certain period in the formation of encli layer.

The increment in gain in the vformation of the conical layers may be such as is found desirable. ln practice, l have found an initial incremental xruin of about one sixty# tonrtli 'of an inch to produce excellent -re snlte in, winding fl0s. 'llic described incregain is added at or 'in the Weaving operation. The i,

Liaison mental increase in the lengths o the layer need not be etected between successive traverses, but may instead 'be eec'ted between successive series of traverses, said series A'loolobins but preferably of a generally tapering form and Without a marked or abrupt conical shoulder at the 'base to receive 'the rst laid layers and to impart the desired chase or taper as largely heretofore practised. 'By omitting said shoulder l am en 'ahlecl to spin an increased length of yarn upon the receiver. lt is, however, to he understood that yarn packages may he wound upon Acop tubes of paper or the like or other carriers or even upon' nare spin dies.V `While the loobbin may be of any euitable shape, it is preferably oi'' gradually decreasing diameter from substantially its lower end to its tip and may be of smaller diameter than heretofore. lf desired, and especially Where the yarn package is to be used in a Weaving shuttle, l forni a cuneh il by imparting short traverses, as, for ei:- ample, about three eiglitlis of an inch in length and involving lout a .few conical layers. lmmediately after the formation or" such bunch, the gain and traverse may lie abruptly increased., so that the immediately succeeding layers 3 are Wound with an open coil. As here represented, tlie length of taper of the coils 3 is substantially seveneighths of an inch. `Thereafter the gradual increase in the length of the taper com menoes with the described pro ,essi-rely :increasing gain throughout the packageancl at l in llig. 3 l have indicated e conical layer of slightly increased taper over that indicated at Sxin 2; y This increasing traverse and progressively increasing are here represented as continued until the base ,ofthe yarn 'package is completed. Thereafter the nnilerinincrcase in the trai ferse is continued and the gaini'sniaintaincd j uniform-until' tlicfpaclmge ie'loultupas indii-cated at 5 in Fig. 4 and terminates with a layer 6 here shown as of substantially one and a'lialf inches, but which may .be even more; The package 'when thus Wound is cylindrical throughout the body portion ingly difficult matter to unwind the ceedingly apt to lorealr when the'tunell reached in the paying oil. of the lyarn nu being 'formed during the upwarc movement o the 'ring rml or other glude, und that ren resented in Fig, 6 at 8 being; formed ioe succeeding downward movement.

While I have herein referred to the up-I` wardly and downwardly Wound layers, it is evident that these terms refer merely to that position in which the yarn package is customarily Wound. It is, of course, to be understood that the. yarn package may be Wound or formed in any suitable position.

It is of extreme importance that thev initial traverse be of the'minimum length,

thus causing the first laid layer to be ,the

shortest, and that these layersy gradually increase in length, since thereby in 'the unl Winding of the cop in the Weaving operathe base, and hence there is increasingly less friction and resistance or drag to the un- Winding of the yarn of the successive layers as the distance increases between the eye of the shuttle and the point at which the yarn leaves the bobbin or other package carrier. Since the drag thusbecomes proportionately less as the' distance'between theyarn mass and the eye of the shuttle increases,that

is, since the friction andl drag opposed to the unwinding'of the yarn in the Weaving operation, are inversely proportional to the distance of each layer from the feeding eye "of the shuttle`,because of the increasingly greater length of the layers toward the tip of the bobbin or other carrier, there is effected a 'substantiallyy even tension on the yarn as laid in the cloth'. If the Winding begins. with a minimum traverse," but with Ea gain of the full or ultimate value, the result would be that the early layers or traverses .would be too long, and the desired results as regards evenness in the yarn tension would not be secured. .By providing, however, agminimumgan as well as a'minimum traverse, the ideal condition is secured, and by increasing the traverse andthe gain, the uniformity of tension is not impaired., This result is secured by increasing the'l gain and more especially by progressively increasing the gain. a ,v

- The ideal condition is presented by progressively increasingl the gain from the minimum, inasmuch as I thereby,` in the early llayers, .obtain very'short traverses with the advantages above'set forth, and at the same time each layer begins safely above winds with which I am familiar. tion, the length of layer gradually becomes' less and less from the tip of the cop toward incassa the commencement of the preceding layer.

full diameter of the yarn package more quickly,'a nd hence more yarn is lWound onto `the package at` its base, Without, however,

obtaining longer traverses at this point.- In my yarn package, yas the yarn is unwound from the base toward the point of any layer,

the turnsof the yarn are found to be separated, thus preventing one turn ofv yarn pulling oil' another, which 1s not true of yarn' packages with which I am familiari In practice, it isi'unnecessary to clean i the bobbin after weaving, since the entire yarn Winds cl'l". This is. not true of other form of the bobbin at itsbase usually used heretoforewto sta-rt the spinning, and hence I am enabled to Winda correspondingly additional amount of 'yarn on the bobbin.

In practice, I' have discovered that'the in-y itial short layers woundl in accordance with my invention constitute in themselves a very egective bunchf4 and that it is notnecessary to have a. special bunch. v'After forming such substitute for a bunch, theV Winding can proceed in the same manner,

Whereas in most bunchfforming Winds with I have also been able to dispense with the conical in contact with the' bunch, andthis creates unevenness in the tension and tends to break the yarn; I am enabled to svind the yarn upon the carrier with even tension from end to end. By decreasing the friction, as here,

heavier traveler, which is a desideratum, inasmuch as" the heavier tl1e traveler, the tighter the Wind. c l Having thus described. one illustrative embodiment of myv invention and the .best

same, I 'desire it to be understood. 'that are used in a generic and descriptive sense method known to me for practising the l and not for purposes of 'limitation,'the. scope ofthe invention being set forth in the following claims.
